Lexus LX 470 Gains Power, Adds Enhancements for 2006

[hoser]

I'm no expert on how it or the tranny works, but I notice a change. It feels as though an extra set of "gears" or the ratios are different somehow. Sorta like it's got more gears. I can easily do 4-wheel drifts with it engaged.

I definitely notice the difference. In both settings, if you floor it, the shift points will be about the same but if you drive normally, with the ECT engaged, the tranny will shift at a higher RPM---or "hold the gear" longer.

I just assumed, since I cannot detect any difference whatsoever with ECT switched on or off, mine wasn't working. However I didn't actually try it with the pedal to the floorboard...

I had a Saab 9-5 that had it...and it definately worked. Our current Audi A-4 has it and it definately works. And was/is useful.

Spresso-I'm not saying floor it, reread what I wrote.

But perhaps because you live at a higher elevation, your tranny might shift at a higher RPM anyway (ECT off or on)? I'm just guessing though.

I should slow down and read more carefully...must be to much espresso

Anyway...one of these days when I am real bored I plan to spend a little time tracking down the ECT circuit to see if it might be a connection problem...but it's definately way down on the list.

Put the Escalade push-rod, antiquedated, gas hoggin', 30-year old engine design in a 100 and call it a day if that's what you need...

Much as I love my LX and the 2UZ, the power, as I think most would agree, leaves something to be desired. That said, if the above retrofit were "reasonably easy"/possible, I'd be inclined to do it to have "adequate" normally-aspirated power (LS1 or better, as I've had SBC's run on dino oil for 300K+ without as much as a timing chain replacement)........Again, LOVE the 2UZ, but needs more power

Flame away.............................

Faster yes, though all the qualities (smoothness, silence, overall refinement) are out the window. The Chevy motor would be a grade down off-road too. The Toy V8 makes 90% of it's torque at an unheard of 1100RPM.

 

[FirstToy]

I think you guys should drive the VVT-i V8. Toyota seems to constantly refine it's products every year and adds something or improves it. The VVT-i 4.7 is a big improvement.

The VVT-i technology allowed a 4.0 6cyl to come within 20 ft/lbs of the 4.7 V8 and now that they put it on the V8, it's top choice, imo. The 05 UZJ is def. the best one (sans factory rr locker).

Regardless, the 100 is so frickin' smooth. It does feel slow but its so refined I just didnt care. Maybe owning one, you get used to it and start wanting for more giddyup.

Mid to top-end yes. Down low, no improvement. I'll take the "even power curve" on a Cruiser V8 any day. I'll take the VVTi on a sports car or maybe sport Tundra-ee truck.

Are you saying the '05 is available with a RR locker? I didn't see it part of any options package.

 

[tabraha]

He's saying except it doesn't come with the rear locker.

Actually, according to Christo's dyno, a little more top end would make the power curve even flatter.

 

[ShottsUZJ100]

Actually, according to Christo's dyno, a little more top end would make the power curve even flatter.

Unfortunately you'll see no change really. The VVTi is only a gain of 5 ft/lbs of torque (325 vs 320). All the gain is in HP at the higher end of the spectrum.

The heavier the vehicle the more torque (not HP) we need. That's why diesels work so well on these heavy rigs. I think all of us would be happy with the 235HP but we'd luv it if the tirque spec went to say......oh......400.

 

[hoser]

Sure, you'll see a change in torque. True, PEAK torque is only up 12ft/lbs but the total area under the torque curve will be greater. Peak torque on Christo's dyno happens at about 3500 rpm and then slopes down. I would imagine the newer VVTI engines to maintain a flatter torque curve all the way up to 5250 RPM where Torque=HP.

Hmmmm, could be I guess. You may have a good point.

 

[dclee]

Agreed. Most Toyota diesels (in fact, ALL of them I think, including the turbo) have less peak torque than even the venerable 1FZ-FE. Even the military HMMWV only has 250 lb.-ft. The advantage is that they make all of it WAY down low.

So really, what that says is higher numbers aren't always the only answer, but more in how they're delivered, i.e. quality vs. quantity.

 

[macneill]

But I think it comes with DCLEEs roof rack standard.

Do you guys think this buys Toy another couple of years with the 100 series in light of the 2006 enhancements? Hard to imagine why Toy would go through the trouble of updating the engine and make the aformentioned cosmetic/mechanical changes and then redesign for 2007 model year.

 

[calamaridog]

Sales have been fairly consistant of the LX470 and LC. The updates make sense, to remain appealing to the new car buyers. Producing two versions of the 4.7 doesn't make sense either, much better to switch all products to the VVTI motor.

I will look forward to having the VVTI motor in about 5-6 years when I get my new, used UZJ100

Ditto...you read my mind. And all the mods on my current swap right over...how cool is that!!! Thanks Toyota! In all the years and GM models I have owned I can't ever remember thanking GM for anything but pain and misery

The cosmetic changes are minimal. Most car manufactures make slight changes every 2-3 years as well. As for the engine, the cost to change is also offset by the savings in using the same engine across their entire model line-up. In a few years when I want to replace my 98, I'd definitely pay more for a 06 over an 05 for these improvements.
